LS1 Throttle Body / PCV Hose Combo Question Recent 2002 Camaro purchase. My A/C was not working. The small vacuum hose that attaches to rear of intake to HVAC Check Valve had no vacuum. I couldn't get my hands around the back of the intake all the way. I decided to pull intake off. I studied the forums here for a week or so prior to doing the job. From all that I read I went ahead and ordered a new PCV Hose, Intake gaskets and OPSU. So questions this, there is a fitting at top of Throttle body. This fitting connects a hose to passenger valve cover. Is this fitting part of PCV system? It was completely clogged on the throttle body. Car ran great despite having a rotten PCV hose that was broken in 3 places, in other words completely non functioning and the clogged TB to PCV hose. Was the computer just compensating for all this? Is there anything to look out for during reassembly?
Thanks,
Rob

Did see that hose was a vent hose for PCV However if it is a vent hose with fresh air coming from front of Throttle body. Why would it plug up so bad???

Possible but hard to say. I used to have a similar issue with that hose getting saturated with oil, and realized I recently starting consuming oil (about 1 quart every 1000 miles) and took that hose off and capped the ends on the passenger side valve cover and TB, and instead ran a hose from the drivers side TB to the PCV valve, and that stopped the oil issue. I'm running a breather as well. How much oil do you go through?

Looking at Intake and see another problem Not to sure of oil consumption. Just got car several weeks ago. The car is bone stock and well taken care of. Between the Throttle Body and intake the gasket was blown through as well. I'm not sure but could it have been the janky leak between the TB and filter housing. Unfiltered air was def getting through. I guess ill replace the gasket between the TB and Filter housing as well. Any ideas?
Thanks,
Rob

Got it all back together. It ended up being super simple to finish this. I removed Intake. Replaced rotted PCV hose with updated Factory PCV Hose setup. Put a new Map sensor and Camshaft Sensor O-ring. Replaced the OPSU Sensor as all through the forums you guys stated it would break due to age when i removed intake. Which it did. Replaced all the Gaskets. Buttoned her all up. Changed oil over to Mobile 1 and went with the ACDelco filter. This was easy with all the help I got from here. The searching was the hardest part. Thanks for all the great info. Catch can is in the very near future. Dealing with some suspension problems now.
Again Thanks,
Rob
